01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or lightly grease it with nonstick spray.
02 - Pat the chicken breasts dry with paper towels to ensure proper seasoning adhesion and even browning.
03 - In a small bowl, combine the olive oil, salt, black pepper, garlic powder, paprika, dried thyme, and onion powder until well blended.
04 - Rub the seasoning mixture evenly over both sides of each chicken breast, ensuring full coverage.
05 - Place the seasoned chicken breasts on the prepared baking sheet, leaving space between each piece for even air circulation.
06 - Bake for 20 to 25 minutes, until the internal temperature reaches 165°F when checked with an instant-read thermometer and juices run clear.
07 - Remove from the oven and let the chicken rest for 5 minutes before slicing to allow the juices to redistribute.
08 - Garnish with freshly chopped parsley and serve alongside lemon wedges if desired.
